Scientists have learned a great deal from studying and using stem cells. "Bird flu diseases" are not involved in stem cell research.

Explanation:

The cells aimed at distinguishing the cells into specific kinds, serve as the possibility of a natural source (renewable) of substitute cell and flesh to cure various diseases named as stem cells. This involve back bone injury, vision loss, burns, cardiac related issues, blood sugar, stroke, and some arthritis.

Avian influenza or bird flu is a viral illness which can kill birds as well as humans and other species who consume them or in contact with them. H5N1 is the most frequently seen form of bird flu.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
